"Method 1
 
I had this problem once after writing with empty battery.Kess v2 master says all ok,but after this,the car crank but not start. Cooling ventilator works.Helps to write the ecu in BDM mode.But first you need full 
BDM for it.My tuner have prepaired file for me to write it.After writing,I can read out it 
an make DPF off.

Method 2 : Change read speed to slow

If this does not work,leave ignition on position two for 30- 40 mins,They try to read ECU 
without tunring ignition off when Kess 5.017 ksuite  2.23 software  ask.

Method 3 : Connect and correctly choose driver
 
1.)Choose setup,in options IENTIFY ,READ,WRITE,RECOVER,SPECIAL and Setup
2.)Choose Speed, in 2 options PULL UP and Speed
3.)Select MINIMUM, in 2 options MINIMUM and MaxiMUM
Note these options do not appear to be sticky so you must do this for each attempt"
